An Algebraic Model for the Pion’s Valence-Quark GPD: A Probe for a Consistent Extension Beyond DGLAP Region Via Radon Transform Inversion

We briefly report on a recent computation, with the help of a fruitful algebraic model, sketching the pion valence dressed-quark generalized parton distribution. Then, preliminary, we introduce on a sensible procedure to get reliable results in both Dokshitzer–Gribov–Lipatov–Altarelli–Parisi and Efremov–Radyushkin–Brodsky–Lepage kinematical regions, grounded on the GPD overlap representation and its parametrization of a Radon transform of the so-called double distribution.
